ROSE-ENGINE `i?ECIFIGATIOIl' forming part of Letters Patent No. 314,064,elated March 17, 1885. i

Application ii'ed January l5, i985. (No model.)

To @ZZ whom, it may concern.-

Beit known that I, ANTON SeH'WrT'rne, a citizen ofthe United States,residing at Brooklyn, in the county ot' Kings and State of New York,have invented new and useful Improvements in Roselngines, oil which thefollowing is a specification.

This invention relates to a rose-engine which produces rectilineardesigns or designs composed of ri ghtlines,in contradistinction toroseengines which produce curvilinear designs.

My present invention consists in the combination, with the graver ortool-support, of the pattern-slide, the screw-spindle for imparting tothis slide the required motion, the Work -support, the carriagesupporting the pattern-slide and the work-support, the tracerslide, astop which retains the graver out of Contact with the work when thetracer is opposite to oneof the high portions of the pattern, and meansfor imparting to the carriage a reciprocating motion, so that byimparting to the carriage, the graver-support, and the pattern-slide therequired movements the de; sign contained on the face of the pattern isreproduced upon the face of the work. With the tracer-slide and thecarriage is combined a pantograph connection for changing the scale ofthe reproduced design. cured to an arm, which is hinged to thetracerslide and which bears upon a projection eX- tending from thegraversupport, so that the osition of the 0raver in reward to th'e Workb b is automatically controlled by the action of the tracer upon thepattern.

In the accompanying drawings. Figure l represents a sectional front viewof my roseengine, the plane of section being indicated by the line x x,Fig. 2. Fig. 2 is a longitudinal vertical section in the plane y y, Fig.l. Fig. 3 is a horizontal section in the plane z a, Fig. l. Fig. 4 is aface view of the pattern on a larger scale than the previous figures.Fig'. 5 is a face View ofthe Work produced from this pattern whenone-half of said work has been finished. y

Similar letters indicate corresponding parts.

In these drawings, the letter A designates a frame, into whichV islit-ted the carriage B, so

5o that said carriage can be moved up and down.

Various means may be used for imparting to The tracer is se-` thecarriage this up-and-dow'n movementsuch as a rack and pinion or suitablelevers.

ln the example represented by the drawings l have shown a spindle, C,which has its bearings in the head D, and on which is mounted a drum, E,from which extends a rope, cord, or chain, c, to the carriage B. Fromthis carriage extends another rope, cord, or chain, b, over one or morepulleys, c, and to the free end of this rope is secured a weight, e.This `weight slightly overbalances the weight of the carriage with allthe parts connected to it, and when the spindle C is turned so as towind up the rope a on the drum E, the earriage is depressed; but if thespindle is turned in the opposite direction the carriage is raised bythe action of the weight. The spindle C is turned by a treadle, whichconnects by a belt with a pulley,f, mounted on the spindle, (the beltand treadle being not shown in the drawings.)

On the carriage B are mounted the Worksupport F and the pattern-slide G.In the example shown in the drawings the Work-support is secured to a.slide, II, which is fitted into guideways extending transversely acrossthe carriage; but it' it is desired to reproduce on the work onlyrectilinear designs, the work-support may be rigidly secured to thecarriage. The patternslide G lits into guideways g, formed in thecarriage or in a casting firmly secured to said carriage, and ascrewspindle, I, serves to impart to said pattern slide a movementtransversely to the carriage or in a direction at right angles to therising and falling movement of said carriage.

On the pattern-slide is firmly secured the pattern J, on the face ofwhich is engraved, etched, or otherwise produced a counterpart of thedesign which is to he reproduced on the face of the ivorlthat is to say,if the work is to be ornamented by diamonds produced by rightlines ofgradually increasing and decreasing length, leaving diamond shaped blankspaces between them, as indicated in Fig. 5, the pattern consists ofdiamonds which are alternately raised and depressed, and when the tracermoves over one ot' the depressed panels or sections of the pattern, thegraver produces the lines on the work,\vhile, when the tracer moves overone of the raised panels or sections of the pattern, the graver ispushed away from the work, as will be presently more fully explained.

The tracer h is secured in an arm, I,which is hinged to theytracer-slide L, so that when the tracer is moved over the face of thepattern, it can fall into the depressed panels or recede, so as to moveover the raised panels of the pattern. The tracer-slide L moves up anddown in guideways z', Fig. 3, formed ina standard, M, which is firmlysecured to the base supporting the frame A, and it connects by the rodN, lever O, and link I) with the carriage B. The lever O has its fulcrumon a pivot, j, which can be adjusted in a slot, Zr, so that by movingthecarriageB up and down more or less motion is imparted to the tracer"-slide L. If the fulcrum j is adjusted directly in the middle of thelever O and the carriage B is depressed, the tracerslide moves np justas much as the carriage moves down; but when the fulcrumj is movedtoward the outer end of the lever O, the movement of the tracerslide isdecreased, and vice versa, and by increasing the movement of thetracer-slide the scale of the design produced on the work is reduced,and vice versa. lf it is desired to enlarge the scale of the designproduced on the Work, the fulcrum j of thev lever O must be placed in anextension of said lever beyond its connection with the rod N.

I have termed the rod N, lever O, link l?, and the adjustable fulcrnm jof the lever O the pantograph connection between the carriage and thetracer-slide.

The arm K,which carries the tracer h, bears upon a pin, Z, which issecured in an arm, m, projecting from the support Q of the graver n. Thesupportis of well-known construction, and it can be moved toward andfromthe work in guideways o, and also across the work in guideways p.

Then the operation commences, the tracer is supposed to be opposite oneof the depressed panels in the pattern and the tool support is forcedinward by a slight pressure of the hand or otherwise, so that the pin Zbears upon the arm K of the tracer and that the graver bears upon thework. The carriage is then depressed and allowed to rise, and the graverproduces the first line on the left-hand side of the work, Fig. 5; thenthe pattern-slide is moved in the direction of arrow l, Fig. l, and thegraver is moved in the opposite direction, as indicated by arrow 2, thecarriage B is again depressed and allowed to rise, and ther second lineis produced on the work. As the operation progresses the lines producedon the work by the graver become broken, because whenever-the tracerpasses over one of the raised panels of the pattern, the graver is, bythe action of the arm K on the pin Z, forced back out of contact withthe work; but for each down-and-up stroke of the carriage the graver iscarried up and down over the entire face of the work.

The pin Z, secured to the arm m of the graversupport Q, bears againstthe arm K, which carries the tracer 71 and these devices, orequivalent,constitute what I term a stop,7 which, by pushing on the graver-support,retains the graver out of contact with the work when the tracer isopposite to one of the high portions of the pattern.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbefore described, with thegraver-support, of the pattern-slide, the screw-spindle for imparting tothis slide the requisite motion, the work-support, the carriagesupporting the pattern-slide and the work-support, the tracer-slide, thestop which retains the graver out of contact with the work when thetracer is opposite to one of the high portions of the pattern, and meansfor imparting to the carriage a reciprocating motion. v

2. The combination, substantially as hereinbefore described, with thegraver-support, of the pattern-slide, the screwspindle for imparting tothis slide the requisite motion, the work-support, the carriagesupporting the pattern-slide and the work-support, the tracer-slide, thestop which retains the graver out of contact with the work when thetracer is opposite to one of the high portions of the pattern, thepantograph connection between the carriage and the tracerslide, andmeans for imparting to the carriage a reciprocating motion.

3. rlhe combination, substantially as hereinbefore described, with thegraver-support, of the pattern-slide,'the screw-spindle for imparting tothe slide the requisite motion, the work-support, the carriagesupporting the pattern-slide and the work-support, the tracerslide, thearm hinged to the tracer-slide and carrying the tracer, the pinprojecting from the graver-support and bearing on said arm, and meansfor imparting to the carriage a reciprocating motion.

4. The combination, substantially as l1ereinbefore described, with thegraver-support, of the pattern-slide, the screw-spindle for imparting tothe slide the requisite motion, the work-support, the carriagesupporting the pattern-slide and the work-support, the tracer-slide, thearm hinged to thetracer-slide and carrying the tracer, the pinprojecting from the graver-support and bearing on said arm, thepantograph connection between the carriage and the tracer-slide, andmeans for imparting to the carriage a reciprocating motion.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
